hill. is FOR CONVERTING RECIPROUATING'INTO ROTARY MOTI EON.

Specification of Letters Patent.

Application filed March 28, 1810. Serial No. 552,050.

To all whom it'ma'y concern:

Be it known that I, FREDERICK LAMP- LoUGH, a subject of the King of Great Britain, residing at London, England, have invented new and useful Means for Converting Reciprocating into Rotary Motion, of which the following is a specification.

The invention relates to means for obtaining rotary mot-ion of a. shaft, and consists in the combination and arrangement of parts herein shown and described.

I will describe my invention by means of the accompanying drawings, in which-I Figure 1 is a face view, Fig. 2 is a plan, and Fig. 3 is a horizontal section.

a is the shaft to which rotary motion is to be given.

b is an angularly' set disk fixed on the shafta. l

e is a yoke which is oscillated by a prime mover about an axis at right angles to and passing through the axis of the shaft a. The power transmitted to the oscillating yoke ejs applied to the angularly set disk I) at points equidistant from and on a line which passes through the axis of theshaft a and is at right angles to the axis of oscilla-' tion referred to above. A pair of diametrically opposite conical rollers c are located with their centers of rotation on the line aforesaid and have their axles c'.mou'nted in bearings1e"'carrie d by the yoke e. These conical rollers c fit within a tapered annular angularly set disk I).

The, yoke 0 has trnnnions e= mounted in fixed gbearings f and it is formed or providedwith two levers 9 arranged on opposite sides of the shaft a and connected by. links or connecting rods Z to a prime mover,

groove or race around the periphery of the not shown. By these means a reci rocati motion is given to the yoke'e, and t is latter, by its conical rollers 0 located within the tapered ripheral groove. of the a ularly set .disk'a and alternately pulling an pushing against said disk, gives rotarymotion thereto and consequently to'the shaft a.

Each of the bearings e for the axles c of the conical rollers 0 may, for constructional purposes, be conveniently fitted within a split socket m and as shown, is provided with two rows of anti-friction balls n, and

Patented Dec. 19, 1911.

a ball-thrust bearing 0 is arranged between the two rows of balls of each bearing.

Means for taking up the wear on the conical rollers 6 may be provided as follows :-A screwed sleeve 1) carrying the outer ball race is screwed into the split socketm and a distance piece 9 is placed between said outer ball race andthe thrust bearing 0 to force the latter with its conical roller 0 forward. In order to preventthe screwed sleeve 1) unscrewing in the spllt socket at, this latter, on each side; of thesplit, is provided with a lug m and a screw or bolt m is used to tighten the split socket m around the sleeve'p.

. I- claim as my invention:

In means for converting reciprocating into rotary motion, the combination of a yoke, trunnions by which said yoke is carrled, levers carried by saidtrunnlons, means for reciprocating said levers, a shaft, a disk disk having a groove in the periphery thereof, two split sockets carried by said yoke; means for tightening said sockets, a sleeve .fixed at an inclination on said shaft, said screwing in each of said sockets, a ball-'bear- 1 in carried by said sleeve, a distance ad acent to said ball bearing, a thrust mg in contact with the distance piece, .a second ball bearing,

actin in said groove, substantially as shown and escribed.vv

a trunnioncarried by I said ball bearings and thrust bearing, and a conical roller carried by said trunnion and In, witness whereof I have hereunto set my hand in presenceof two witnesses.
